    产品信息

    The MCP3905A is an energy measurement IC supporting the IEC 62053 international energy metering specification. The output of the device includes a frequency proportional to the average active (real) power at the inputs as well as a higher frequency output proportional to the instantaneous power for meter calibration. The MCP3905A incorporates two 16-bit delta-sigma ADCs with a programmable gain up to 16, which enable small shunt meter designs for measuring a wide range of Ib and Imax currents. The integrated on-chip voltage reference has ultra-low temperature drift of 15 ppm//°C.

       Supplies active (real) power measurement for single-phase, residential energy metering

       Supports IEC 62053 International Energy Metering Specification and legacy IEC 1036/61036/687 Specifications

       Two multi-bit, DAC, second-order, 16-bit, Delta-Sigma Analog-to-Digital Converters (ADCs)

       Ultra-low drift on-chip reference: 15 ppm/°C (typ.)

       Low IDD of 4 mA (typ.)

      AEC-Q100Grade 1
